The Australian Broadcasting Corp. reported a pilot of a United Airlines flight en route to Los Angeles decided to return to Sydney after a message written on a sick-bag was found in a toilet. The letters "B-O-B" were written on the bag and were believed to mean "bomb on board."
Passengers on the flight were not told the reason for the return of the flight, which after investigation appeared to be hoax. However, some passengers learned of the possible bomb via the media.
Transport Minister John Anderson said passengers should know why their flight has been turned back, but it may not be always possible.
"Judgments have to be made about whether it's wise to tip off somebody who might have done something wrong that they've been discovered," he said.
"There are other factors such as whether or not there might be people on board who simply would not be able to cope with the prospect that their lives were in danger."
